A CORPCRATION OF LACING-TIPPING MACHINE. i

This invention. relates to an improved ma chine for forming tlps on lacings such as shoe lacings, corset lacings, and the like, and

the object of this inventionflis to provide, such a machine that willwrap or fold the lacing fabricabout a stiffening core where it is retained by cement. Y A still further object of the invention is the provision of a set ofcooperating dies for 1 wrapping the fabric about the core and a cutter for cutting the'tip in two. a

A still'further object of the invention is to provide a pair of dies having aspace between them into which the lacing fabric and invention consists'of certain novel features which lies in of construction, as will be more fully described, and particularly pointed out inth'e appended claims.

In the accompanying drawings,

Figure 1 is a top View of my improved tipping machine partly broken away to better illustrate the action of the dies.

Figure 2 is a centralsectional elevationthrough the machine showing the double action of the opearting lever. p

Figure 3 is a perspective view illustrat ng the die plates and cutter. I

Figure 6 is an enlarged sectlonal View showing the core as deposited on the fabric dies.

Figure 7 shows the core locking plate as raised to slide up over thecore and lacing by riding over its cam. r 7

Figure 8 shows the core locking plate in locked position with its l lockmgarms.

. Figure 9 shows the dies ashaving been adcurved position between the vanced and as having wrapped the fabric about'the core-in which position it is held treated, is dried. c

Figure 10 1s a perspective view showing the tipped end of a lacing with the core in until the cement, w'ith which the fabric is position and before the fabric has been wrapped about thecore.

Figure 11 shows the fabric as having been wrapped around the core'of double lengthto be later severed by the cutter. I I

In the forming of lacing tips by my improved machine the lacing is led by aoon- 'tinuous method explained in my co-pending application, Serial No; 722,581, filed June 26, 192%, to this machine,and is treatedat intervals with cement for a short distance,

about double. the length of a single tip.

The next feeding movement of the fabric brings this treated section into the space between the diesof my improved tipping machine in a curved condition, that is crescent shape or concavo-convex in cross sectlon and into this curved and cement-treated portion of the lacing I' deposit a short length of stiffening material, preferably soft metal wire. I The locking plate is then carried forward to cover the space occupied by the core and lacing, to lock'the same be tween the dies, the dies then receive a relative closing movement whichwraps the lacing fabric about the core and at the same time severe the double length of tip the dies retaining the fabric in this wrapped condition until the cement is hardened, which action is hastened by the application of heat thereto; and the following is a detailed de-- scription of the embodiment of my pr t invention l With reference'to the drawings, 15 desig nates the frame of the machine, which is.

provided with a pair of dovetailed ways 16 in which the slide plate 17 is slidably mounted. On the forward end of this plate is mounted a pair of die plateslS between ,which' is located the cutter bar 19. This plate is provided with an opening 20 through which the lever arm 21 operates and the rear end of thisplate is tapped as at 22 to receive an adjustable bolt 23 by is provided with a hardened contact bar 24 which is engaged bythe operatingedge 25 of the hardened contact block 26 on the lever 21. The frame of the machine is also provided with a pair of cooperating die plates 27 which are fixed thereto by screws 2, which plates are spaced slightly apart to receive the cutter bar 19 between them and these die plates serve not only to cooperate with the die plates 18 in folding 'the fabric about the core but also cooperate with the cutter bar to sever or cut in two the'double length of tip.

In operating this machine, when the die plates 18 are withdrawn from operating position, a space 29 is provided between them into which the next length of the fabric to be operated upon is drawn, the fabric 31 is curved by suitable means described inmy copending application, Ser'al No. 722,581, filed June 26, 1924, into substantially crescent shape in cross section, and when 1n this position the core is deposited into this curved and cement-treated portion of the lacing. The core is of such a size relative to the width of the fabric that the edges of the 'fabric completely surround and abut when folded about'the core.

It is found, in order to retainthis core and its lacing firmly inposition during the action of the cutter 191'and the action of the dies 18 and 27 infolding the fabric about the core, of advantage to cover this space 29, which is accomplished by the provision of, plate which is mounted to slide on the slide plate 17 and inorder to lift the forward end of this plate 32 over the core this locking plate is provided with laterally' ex't'ending bearing lugs '33 which ride up over the cam 84'tli'us lifting the forward end of this locking plate over the core and after having been lifted thereover the end 35 of tliislockin'g plate is then forced beneath the guide arms 36 'to press or force'thecore member 30 downward into-the cement and thelcurved portion of the fabric.

The rear portionof this plate 32 as best illiisti'atedin Figure 5, is pressed downwardly into sliding engagement with the slide plate 17 by meansof a bow spring 37 which is mounted on the cross bar 38' andthe tension of this spring may be adjusted by'the screw 39. g

This lock plate is provided with an opening 40 through 'w'liich tlie operating lever 21 also extends, the'opening in this plate 82 being'considerably shorter in length than theopening 20 in the slide plate 17, whereby the firstmovement of this'operatinglever 21 actuates this locking plate 32 to first lift it over the core and then force it beneath the guide bars'36, thena continued forwardmovement of tliislever causes the portion 35 thereof to engage the portion 24 of the slide plate 17 which advances this plate and causes the die plates 18 and 27 to engage the fabric and wrap the same about the core.

In order to operate this lever 21, I have mounted, as is best shown and described in my co-pending application Serial No. 722,581, liled June 26, 1924, a pair of cams which engage this roll 41 at the upper end of this lever, to move it into and out of operating position.

The lower end of this lever is pivoted at 42 on -the adjustable block 43, which block is held by the binding screw 44 which may be loosened to permit the adjustment through the screw 45 to regulate the effec-- tive stroke ofthe lever 21.

lt'has been found in practice of advantage to provide heat in my improved tipping ma' chine and I have herein shown an electric heater 46 which heats the machine"and-especially the dies and serves to greatly hasten the drying action on the cement.

My improved lacing tipping-machineis very simple and practical in construction and ei'ective in its operation and by it's use the tips may be formed on the "lacing successively by a simple operation ofa single lever which is caused to hold the fabricabout the core, cut it intwo,'and also retain the" I desire it to 'be understood that I reserve the privilege of resorting to all the 'mechanical changes to which the device is susceptib'le, theinvention' being 'defi'nedhnd limited only by theterms ofthe appended claims.
